You are both right. Kinda
Apple does not allow the same IAP to be shared between multiple apps. So technically, you could purchase level pack #9 4 times (Creeps, Creeps Zero, Creeps HD, and Creeps Holiday Edition). Which would suck, because they are the same levels.
I have used a kind of work around that allows your purchases in one version to unlock those same level packs in another version. But it only works if the two versions are installed on the same device.
SO, if you wanted to buy a level pack (or the All Access Pass) on your iPhone, then later on decided you want to also have them on your copy of The Creeps! HD on your iPad (a different device), then you can do it without paying again. Simply install the iPhone version (the one you made your purchase in) on your iPad. Use the "restore" option on the level select screen (of the iPhone version!) and it will unlock your level packs for ALL versions of The Creeps! that are installed on that device (that means your Creeps! HD just unlocked level packs even though you didn't buy them through The Creeps! HD). This is the best I can do until Apple allows multiple apps to share IAPs.
There is still the matter of your scores though. As it turns out, Apple has a similar restriction for Game Center... multiple apps cannot share a game center score board. I'm hoping to work around this limitation in the next update using iCloud. This could also make sharing level pack purchases easier. I don't know for sure if it will work, but if it does, you'll see it soon!
